I'm one of those that prefers the 1500 over the 1800. I love the 1800's power and cornering ability and the few extra mpg is also nice. For me that where the advantage ends. The ride, room and cost far outweights the other advatages for me. If I'm not comfortable the ride isn't good so it's not money well spent. If I was 200 pounds lighter, 2 inches shorter and had some deep pockets I'd own one. I hate it that my knees hit the fairing on the 1800. The biggest issue I have with the 1500's is chassis and fork flex in the fast corners. I call the 1800 the "Fat mans Hayabusa"Not trying to rain on your parade, but there are lots of riders out there that prefer the 1500 over the 1800,realizing a lot of it has to do with the type of riding done. I have ridden both,the power of the 1800 is awesome,but i just wasn't as comfortable on it.Enjoy the ride,whatever you're sitting on!
